Beginning September 6, 2022 the Identity Cloud databases that store user profile records will all be upgraded to a newer major version of PostgreSQL. This upgrade requires each database to be offline for 30-to-60 minutes. During that time, users won’t be able to login or register, and customers won’t be able to access user records by using Identity Cloud APIs.
Don’t confuse this operation with a minor version upgrade, an upgrade that typically requires about 60 seconds of downtime. This is a major version upgrade that, again, requires 30-to-60 minutes of downtime.
Every 3-to-4 years, databases within the Identity Cloud need to undergo a major upgrade in order to remain on supported versions of PostgreSQL. This year, Amazon Web Services (AWS) requires outdated PostgreSQL versions to be upgraded by November 11, 2022. If the databases aren’t upgraded prior to that cutoff date, AWS will automatically upgrade each database sometime after November 11th.
Performing this upgrade enables the databases to remain on current versions of PostgreSQL for another 3-to-4 years.
Given the November 11, 2022 hard date, Akamai prefers to perform these upgrades during times of relatively low customer activity. Typically these low activity times occur right before the end of summer, and before customers start preparing for their fall and winter campaigns.
In our testing, each database typically takes about 20 minutes to upgrade. However, experience shows that a few of the upgrades might take longer. Because of that, customers should expect a downtime window of 30-to-60 minutes. During this downtime, the database will be offline. That prevents the following activities:
- API access to records
Users who are already logged in are typically unaffected when the database goes offline. The users most likely to be affected are those trying to log on after the database has gone offline, or users trying to create a new account. Logins and registration will be allowed as soon as the database comes back online.
Note that the actual upgrade is carried out by AWS but is initiated by Akamai.
Akamai performs upgrades during region-specific low traffic times. The upgrades take place over the course of several days, which enables Akamai to target specific regions at specific times, and to learn from each region along the way.
